India Sets Guinness World Record for Steel Slag Road as Minister Pushes Waste-to-Wealth Infrastructure

Union Minister of State (Independent Charge) for Science and Technology Dr. Jitendra Singh announced that India's indigenous steel slag road technology can reduce highway construction costs by nearly 40 percent while providing four times the structural strength of conventional asphalt roads. Speaking following the conferment of a Guinness World Record for constructing the world's longest steel slag road at Raigarh in Chhattisgarh, Dr. Singh advocated for scaling up the technology across states, government departments, and private infrastructure developers.

Developed by the CSIR-Central Road Research Institute (CSIR-CRRI) in collaboration with steel industry partners, the technology transforms industrial steel slag into durable road construction material. Infrastructure experts noted that highways built with steel slag require major maintenance only after approximately 15 years, dramatically extending maintenance cycles and conserving natural aggregate resources mined from quarries. The initiative directly supports the national 'Waste to Wealth' policy, creating a sustainable solution for industrial byproduct management while significantly lowering expenditure on national highways and urban corridors.
